MACHINE FOR'SCOURIN Gr `KNIVES AND FORKS.

Specification of Letters Patent Nlo. 8,646, dated January 13, 1852.

To all whom t may concern:

Be it known that I, CHRISTOPHER AU- MooK, of the city of Columbus, inthe county of Franklin and State of Ohio, a citizen of the United Statesof America, have invented a new and useful improvement on scouring orpolishing machine for scouring or polishing knives and forks or anyother implements made of metallic substances; and I do hereby declare,that the following is a full, clear, and exact description of theconstruction andoperation of said machine, reference being had, to theannexed drawings, which make a -part of the specifications.

Figure L descriptive, and elevated view of said machine, with all theparts put together. Fig. 2, is a representation of the two cylinderbrushes, which when in operation, do the work of scouring or polishing.

`Letter A in Fig. l is the balance wheel; letter B is a handle attachedto the balance wheel, for the purpose of operating the machine; letterC, is the shaft, on which the balance wheel hangs, said shaft resting onits journals, in bearings in the posts of said machine; letter D is abox in which the cylinder brushes are hung, and inclosed while saidmachine is in operation, which is set in the frame; letter E is cover ofbox; letter F is posts, and letter G is rails, which constitute theframe, of said machine.

Letter H Fig. 2 is cylinder brushes which llie 1n a horizontal positionwhen hung in the box, and when the machine is in motion, revolve ontheir axis toward each other in such a manner that the bristles, orwhatever substance the cylinder brushes are composed of mash into eachother say one eighth of an inch, and at the same time, the lower surfaceis in a liquid polishing or souring vsubstance, held by the box,composed of alcohol, or any other liquid that may be chosen, mixed withbrickdust, emery or any other material used for scouring or polishing. I

Letter I Fig. l is pulleys on the ends of the shafts that run throughthe cylinder brushes; letter K is belt running over balance Wheel andpulleys operating the cylinder brushes; letter L is friction pulleyattached to post for belt to work over; letter M is bearings, in whichthe journals of the cylinder brushes rest, which are so con..

structed, that the brushes may be made to revolve closer together, orfurther apart, at the pleasure of the operator.

I claiml The construction of this machine composed of two cylinderbrushes with their peripheries in contact which causes the frictionnecessary for scouring or polishing, and at the same time keeps thecylinderbrushes which do the work of polishing or scouring wet with thepolishing substance continually, while the machine is in motion, byimmersing the under side of said brushes, in the liquid, a's theyrevolve around on their axis as above mentioned; the article to bescoured or polished, must be held in a perpendicular position, and movedup and down between t-he cylinder brushes, while in the act of scouringor polishing.
